Hi there
We did some research into your problem, and it appears that one of two things could cause that specific error code:
1. The first is a malfunction on the check valve (non-return valve) in the high-pressure fuel pump, which causes a fuel pressure drop in the fuel rail after the engine's been off for a while. If this is the case, a replacement high-pressure fuel pump (HPFP) will remedy the problem, but it's bound to be expensive.
2. The second possible cause is either a broken circuit (connection) to the fuel pressure control valve in the fuel rail, which could send an inaccurate signal to the ECU. In this case, start with the wiring connections to the pressure control valve, and if that doesn't remedy the problem, replace the control valve itself. This is also likely to be pricey, albeit a lot less so than if it were the HPFP.
Hope this helps!
